there is no show-action command to learn how to use an action from the cli

[Richard Harding]

When looking at actions I can see the list with

  juju actions percona-cluster
  backup Full database backup
  pause Pause the MySQL service.
  resume Resume the MySQL service.

However, I can't figure out how to use an action just as backup in this case.

I'd like to have an option to show an action to get details about it.

  juju show-action percona-cluster backup
  description: Full database backup
  params:
    basedir:
      type: string
      default: "/opt/backups/mysql"
      description: The base directory for backups
    compress:
      type: boolean
      default: false
      description: Whether or not to compress the backup
    incremental:
      type: boolean
      default: false
      description: Make an incremental database backup

+1 on this, it's currently not easy to show users the defaults from `actions.yaml` without dumping the whole file with `--schema --format json` and gripping with `jq`.

There is a show-action command now and other improvements to the actions UX (and changes coming in prep of 3.0)
